国外青少年群体同一性研究

在对青少年同伴群体的研究过程中,发展心理学者借鉴了社会心理学中的社会同一性理论的有关内容,对同伴群体与个体行为之间的关系进行了初步探究,结果发现,青少年在同伴群体交往过程中获得的群体同一性影响个体的行为,并进一步探究了有关影响青少年群体同一性的因素。本文对目前国外的青少年群体同一性的研究进行了阐述,并指出了将来研究的方向。     

精神分裂症患者团体绘画艺术干预

探讨团体绘画艺术治疗对精神分裂症患者生理、心理和社会功能康复效果。86名精神分裂症住院患者被随机分配到干预组或对照组。干预组被试接受团体绘画艺术干预活动,对照组从事其他康复活动。结果发现,干预组被试阳性与阴性症状量表总分低于对照组被试,大体评定量表分数高于对照组被试,自我概念总分高于对照组被试,生活质量问卷的躯体功能、心理功能和社会功能维度高于对照组被试。团体绘画艺术干预可以缓解精神分裂症患者的精神症状,促进患者自我概念和生活质量的提升。     

真的是“冤有头债有主”吗?基于群体冲突的替代性报复

群际替代性报复是指群体内成员受到外群体成员的伤害后,内群体的其他成员对外群体的其他成员进行报复的现象。这种基于群体水平上的替代性报复很大程度上已经超越了原本的侵犯者和受害者,而涉及到群体双方更大范围的其他人。替代性报复是一个复杂的心理过程,其产生和程度受到伤害感知、群体认同、外群体实体性、群体情绪以及内群观众效应的影响。内群体在实施替代性报复后也往往存在较为一致的"正面"认知评价和情感体验。未来还需要继续在学术层面上整合和完善替代性报复的心理机制,探讨不同文化观念下替代性报复的特点,最重要的是结合社会现实提出减少替代性报复的策略。     

Confidence in Dyadic Decision Making: The Role of Individual Differences

Groups typically express more confidence than individuals, yet how individual‐level confidence combines during collaborative decision tasks is not well understood. We prescreened 686 community members using a novel confidence measure (a true/false trivia test) intentionally designed to be difficult (accuracy rates were not significantly better than chance) and randomly assigned 72 individuals to collaborate on a matched version of the same test in dyads composed of two low‐confidence individuals, two high‐confidence individuals, or one of each (“mixed”). Consistent with past research, we found that the confidence expressed by dyads was higher than the confidence expressed by individuals; importantly, however, this pattern varied markedly by dyad type, with low‐confidence dyads showing the largest increase, mixed dyads showing a moderate increase, and high‐confidence dyads showing no increase—despite the fact that all dyads showed similarly low accuracy (about 55%). These results highlight the conditions under which groups express greater confidence than individuals and offer insights for the composition of collaborative decision‐making teams.

For the Win: Risk‐Sensitive Decision‐Making in Teams

Risk‐sensitivity theory predicts that decision‐makers should prefer high‐risk options in high need situations when low‐risk options will not meet these needs. Recent attempts to adopt risk‐sensitivity as a framework for understanding human decision‐making have been promising. However, this research has focused on individual‐level decision‐making, has not examined behavior in naturalistic settings, and has not examined the influence of multiple levels of need on decision‐making under risk. We examined group‐level risk‐sensitive decision‐making in two American football leagues: the National Football League (NFL) and the National College Athletic Association (NCAA) Division I. Play decisions from the 2012 NFL (Study 1; N = 33 944), 2013 NFL (Study 2; N = 34 087), and 2012 NCAA (Study 3; N = 15 250) regular seasons were analyzed. Results demonstrate that teams made risk‐sensitive decisions based on two distinct needs: attaining first downs (a key proximate goal in football) and acquiring points above parity. Evidence for risk‐sensitive decisions was particularly strong when motivational needs were most salient. These findings are the first empirical demonstration of team risk‐sensitivity in a naturalistic organizational setting. Copyright © 2016 John Wiley & Sons, Ltd.     

Generalized and specific components of prejudice: The decomposition of intergroup context effects

Although different types of prejudice tend to be highly correlated, target‐specific and more generalized components can nevertheless be distinguished. Here, we analyze whether indicators of the intergroup context—threat, contact, and neighborhood composition—predict the target‐specific and/or generalized components of prejudice. Using data from the New Zealand Attitudes and Values Study (N = 4629), we build a multilevel model that captures the relationship between social dominance orientation, general levels of neighborhood heterogeneity, symbolic and realistic threat and cross‐group friendship (averaged across target groups), and generalized prejudice. Our model simultaneously estimates the relationship between target‐specific levels of these intergroup context indicators and target‐specific prejudice. Results indicated that social dominance orientation remained the strongest predictor of generalized prejudice when adjusting for other variables and that indicators of the intergroup context primarily explain differences between target group ratings. Aggregate levels of cross‐group friendship also had a small effect on generalized prejudice.     

An Open Trial of Group Acceptance and Commitment Therapy With an Adjunctive Mobile App for Generalized Anxiety Disorder

Generalized anxiety disorder (GAD) is a common and debilitating condition. Effective treatments exist, but they are time- and resource-intensive. This study tested the initial efficacy and acceptability of a novel treatment protocol designed to increase efficiency: acceptance and commitment therapy (ACT) taught in groups and through an adjunctive mobile app. Participants were 21 individuals with GAD who received six weeks of 2-hour group ACT sessions as well as access to an adjunctive ACT mobile app. Significant improvements occurred in worry, anxiety, social functioning, and depression as well as relevant processes (psychological inflexibility, anxiety-related cognitive fusion). In-the-moment improvements were also observed in symptoms and ACT processes immediately after completing mobile app sessions. Treatment was perceived as credible and acceptable overall. However, rates of reliable and clinically significant change were low, and app usage did not correlate with change in worry. Overall, this study suggests that an efficient, brief ACT group intervention combined with a mobile app may lead to improvements in GAD but may not be sufficient for clinically significant change. A detailed overview of the treatment is included, and guidance for clinicians interested in implementing this protocol is discussed.     

人类基因组计划及基因革命对伦理的挑战

人类基因组序列的测定和研究具有重大的科学价值和经济价值,同时,也带来一系列社会问题。基因组计划和基因革命对伦理造成了致命的冲击。人类基因商品化对公正原则提出了挑战;基因设计引发生命唯物化,引起了人类的尊严危机;优生运动有可能违背自主原则和平等原则。人类基因组计划应坚持那些体现了人类及其社会本性、价值和尊严的伦理原则即不伤害人、尊重人、有益于人、公正对待人,以及人与人之间互相团结等。     

民族刻板印象威胁效应

Steele和Aronson (1995)最早提出刻板印象威胁的概念,指出这种威胁使个体担心自己会验证所属群体的消极刻板印象.民族刻板印象威胁表现为个体行为表现下降并影响民族交往.民族刻板印象威胁效应的主要机制是工作记忆受损和不认同.通过提供内群体榜样和进行非评价性测试,可以有效地减轻刻板印象威胁效应.未来研究要准确界定种族、族群和民族的概念,考察民族刻板印象威胁与性别刻板印象威胁的区别,研究不同民族的刻板印象威胁效应.     

最简群体范式的操作、心理机制及新应用

最简群体范式作为研究群际关系的有效工具,受到社会心理学家广泛重视。除经典任务程序、随机分配程序外,新近发展出想象程序、记忆程序、自我卷入、计算机模拟群体互动模式等分类操作。最简群体范式具有随机性、完全匿名性和无关自我功利性等特点,可以从群体推断自我、自我推断群体及社会认同整合三个视角解释其心理机制。目前,最简群体范式在社会认知加工、社会心理偏好、社会互动行为及神经生理反应等领域开始广泛应用。
